LEONARD J. LABOU'NTY,OF LOWELL, MASSACHUSETTS, ASSIGNOR TO HIM- SELF ANDALLEN P. BIGKFORD, OF SAME PLACE.

IMPROVEMENT IN Pl'CK'ER-CHEC'KS FOR LOOMS.

Specification forming part of Letters Patent No. 49,830, dated September5, 1865.

Toall whom 'it may concern:

Be it known that I, LEONARD J. LABOUNTY, of Lowell, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Looms; and I do hereby declare the same to be fullydescribed in the following specification and represented 1n theaccompanying drawings, of which Figure 1 is a side elevation, and Fig. 2an under side view, of it as applied to the race-beam of the loom. v

Myinvention consists of a spring-hunter and an adjustable frame forholding the same and applying it to the breast-beam in such manner thatthe position of the hunter relatively to the outer end of thepicker-staff of the said beam may beadjusted as circumstances mayrequire.

In the drawings, A denotes part oft-he racebeam of the lay of theloom-that is, the part thereof on which the shuttle-box is usuallyarranged. 4

B is a metallic frame formed and placed with respect to the picker-stallslot at in manner as shown in the drawings, and being provided with anelongated slot, 1). The said slot b is for the reception of two screws,0 c, which are to be passed through the slot and be screwed into therace-beam until their heads may come into close contact with the frame Band hold it firmly to the race-beam.

Four short posts or standards, at d d d, extend from the frame B, andhave holes made through them in order that they mayrec'eive,

support, and allow to slide freely through them the legs 0 e of aspring-hunter, G. A helical spring, f, encircles each of the said legs,and abuts at one end against one of the standards and at the other endagainst a collar, 9, fixed to theleg, or held in place thereon by a pindriven down. through the leg. An elastic cushion, h, is applied to thatpart of the hunter which is between its two legs, the said cushion beingcomposed of a strip of leather or other suitable material wound aboutthe said part of the hunter.

I am aware thatit has been customary to em- I ploy at the extremity of ashuttle-box an elastic cushion or spring for the picker-staff to abutagainst, the same being in order to prevent injury to the stafi, as wellas the displacement of the yarn from the spindle of the shuttle.Therefore I make no claim to such a use or application of a spring orcushion, my invention having reference to one capable of being adjusted,as described, for the purpose of preventing the pickerfrom striking toohard against the outer end of the slot of the race beam in which it maytravel, as well as to compensate for the loss of elasticity by thesprings, which, it is well known, are apt to grow weaker while in use.

I therefore claim-,-

The combination of the hunter 0, made and provided with springs, asexplained, with the adjustable holding-frame B, having adjustments,substantially as specified.
